• used to charge an electric vehicle

• diverted towards hot water

• used by appliances

• exported to the electricity grid

​

Whether solar panels are worth installing depends less on simply having a suitable roof and more on how much useful electricity your household can generate and consume.

​

​

Is It Worth Installing Solar Panels on My Home?

 

For many properties, yes.

​

Solar panels can be particularly attractive where the home has:

• a suitable unshaded roof

• reasonable daytime electricity consumption

• an electric vehicle

• battery storage

• plans for future electrification

• relatively high electricity bills

​

The financial case can become even stronger where several of these factors occur together.

​

A homeowner who works from home, charges an EV and operates appliances during daylight hours may be able to use considerably more of their solar electricity than a household that is empty throughout the day.

​

That is why the value of solar is different for every household.

​

​

What Are You Actually Buying With Solar Panels?

 

Solar panels are effectively a small electricity-generating system installed on your property.

​

Once installed, the fuel — sunlight — is free.

​

There will still be maintenance considerations and equipment such as inverters may require replacement during the life of the system, but solar PV has relatively few moving parts.

​

This makes solar fundamentally different from many other household improvements.

​

You are not simply improving the appearance or comfort of the home.

​

You are adding an asset capable of producing electricity for many years.

​

​

What Makes Solar Panels Worthwhile?

 

Several factors determine the value of a solar installation.

​

Roof orientation

A well-positioned roof can produce more electricity than a poorly orientated or heavily shaded roof.

​

South-facing roofs are excellent, but east and west-facing roofs can also provide worthwhile generation.

​

Shading

Trees, buildings, chimneys and roof structures can reduce generation.

​

Limited shading does not necessarily make solar unviable, but substantial permanent shading can affect the economics.

​

System size

More panels generally mean greater potential generation.

​

However, installing the maximum possible number of panels is not automatically the best solution.

​

The system should reflect the available roof space and how much electricity the household can realistically use.

​

Electricity consumption

The more solar electricity you use within your own home, the less electricity you need to purchase from your supplier.

​

Understanding when you consume electricity is therefore important.

​

Future energy use

Your electricity consumption could change substantially over the next few years.

​

Adding an electric vehicle, heat pump or air-conditioning system could increase the amount of electricity you use at home.

​

This may make a larger solar installation more attractive even if current consumption is relatively modest.

​

​

What About Battery Storage?

 

A battery can change the economics of solar considerably.

​

Without battery storage, surplus solar electricity generated during the day must either be used immediately or exported.

​

A battery allows some of that electricity to be stored and used later.

​

For example, electricity generated at lunchtime could potentially be used during the evening when cooking, lighting and other household demand increases.

​

However, battery storage adds significant cost.

​

It should therefore be sized according to the property rather than automatically adding the largest battery available.

​

The question should be:

How much battery storage would this particular household actually use?

​

​

Can Solar Panels Charge an Electric Car?

 

Yes, and this can make solar particularly attractive.

​

An EV represents a significant new household electricity demand.

​

Where the car is available during periods of solar generation, some home-generated electricity can potentially be used instead of electricity purchased from the grid.

​

Smart chargers can also help coordinate vehicle charging with available solar generation.

​

For homeowners planning to move towards electric cars, it is therefore sensible to consider solar panels, EV charging and battery storage together.

​

​

Is a Heat Pump Worth It?

 

A heat pump is a very different investment.

​

Solar panels generate electricity.

​

A heat pump replaces or supplements the system that heats your home.

​

This means the decision is influenced by completely different factors.

​

A heat pump can be particularly worth considering where:

• an existing boiler is approaching replacement

• the home currently uses oil, LPG or direct electric heating

• substantial refurbishment is planned

• insulation improvements are being undertaken

• underfloor heating is being installed

• radiators can be suitably upgraded

• the homeowner wants to reduce reliance on fossil fuels

• solar electricity is also being considered

​

Heat pumps can work extremely well, but successful installation depends heavily on designing the system around the property.

​

​

Solar Panels or a Heat Pump — Which Should I Install First?

 

For many homeowners, this is the more useful question.

​

There is no universal answer.

​

However, the starting point is to understand what each technology actually achieves.

​

Solar panels reduce the amount of electricity you need to buy.

​

A heat pump changes how you heat your home.

​

If your existing boiler is relatively new and working efficiently, replacing it immediately with a heat pump purely because heat pumps are greener may not be the first investment we would recommend.

​

Solar panels, insulation or better controls might provide a more immediate benefit.

​

On the other hand, if your boiler is approaching the end of its life, that creates a natural opportunity to consider whether the next heating system should be another boiler or a heat pump.

​

Timing matters.

​

​

Solar Panels Often Have a Simpler Investment Case

 

Solar panels have one important advantage when comparing them with heat pumps.

​

They can normally be added without changing the way the existing heating system operates.

​

Your boiler can remain.

​

Your radiators can remain.

​

Your hot water system can remain.

​

The solar panels simply begin generating electricity that can be used by the home.

​

For this reason, solar can often be a relatively straightforward first step into green home technology.

​

A heat pump can require greater consideration of:

• insulation

• heat loss

• radiators

• underfloor heating

• hot water storage

• controls

• external equipment

• electrical capacity

​

That does not make a heat pump a poor investment.

​

It simply means it is usually a more fundamental change to the home.

​

​

When Might a Heat Pump Be the Better Investment?

 

There are situations where heating should take priority.

​

Imagine a homeowner with:

• an old oil boiler

• high heating costs

• good insulation

• suitable radiators

• space for a hot water cylinder

• a suitable external heat pump position

​

For that property, a heat pump could be one of the most logical upgrades available.

​

Compare that with a home containing a relatively new efficient gas boiler but a large sunny south-facing roof.

​

Solar may be the more obvious first investment.

​

Different property. Different answer.

​

​

Do I Need to Insulate My Home Before Installing Solar Panels?

 

No.

​

The performance of solar panels is largely independent of how well insulated your house is.

​

A poorly insulated home can still have an excellent solar roof.

​

However, that does not necessarily mean solar should automatically be the first improvement.

​

If the house has extremely poor insulation and high heating costs, addressing obvious heat loss may provide an immediate improvement in comfort and energy efficiency.

​

That is why looking at the whole home matters.

​

​

Do I Need to Insulate Before Installing a Heat Pump?

 

Insulation is more directly relevant to a heat pump.

​

The more heat a building loses, the more energy the heating system has to provide.

​

Reducing unnecessary heat loss can therefore:

• reduce heating demand

• improve comfort

• potentially reduce the required heat pump size

• improve overall system performance

​

But this does not mean every property must be completely insulated before a heat pump can work.

​

Older and period homes can use heat pumps successfully.

​

The important thing is understanding the actual heat loss and designing the heating system accordingly.

​

​

Could I Install Solar Panels First and a Heat Pump Later?

 

Absolutely.

​

For many homes, this could be a very sensible sequence.

​

A homeowner might:

​

Stage 1: Improve obvious insulation and draughts.

​

Stage 2: Install solar panels.

​

Stage 3: Add battery storage if worthwhile.

​

Stage 4: Replace the existing heating system with a heat pump when the boiler reaches the appropriate point in its life.

​

Stage 5: Add an electric vehicle and smart charging.

​

The exact order will vary from property to property.

​

The key is planning ahead.

​

Installing solar today should ideally take account of the electricity the home may consume tomorrow.

​

​

Can Solar Panels Run a Heat Pump?

 

Yes — but this needs to be understood properly.

​

A heat pump uses electricity, so solar-generated electricity can contribute towards running it.

​

However, solar generation and heating demand do not perfectly coincide.

​

Solar panels generate most electricity during daylight hours and considerably more during the brighter months.

​

Heating demand is generally greatest during winter when daylight hours and solar generation are lower.

​

Solar panels therefore should not normally be expected to provide all the electricity needed by a heat pump.

​

But the two technologies can still complement one another extremely well.

​

​

Solar + Battery + Heat Pump

 

This is where whole-home energy planning becomes particularly interesting.

​

A future green home might include:

• solar panels generating electricity

• a battery storing surplus generation

• a heat pump heating the property

• smart controls managing energy demand

• an EV charger using available solar electricity

• improved insulation reducing overall heating demand

​

These technologies do not operate independently.

​

Each one affects the economics and usefulness of the others.

​

That is why simply asking installers for individual quotations can sometimes result in a collection of products rather than a properly considered home energy strategy.

​

​

What About Air Conditioning?

 

Solar electricity can also make air conditioning particularly interesting.

​

Unlike space heating, cooling demand tends to occur during warmer, sunnier weather — precisely when solar PV generation can be strongest.

​

A home generating significant solar electricity during a hot summer afternoon may therefore be able to use some of that electricity directly for cooling.

​

For homeowners considering future air conditioning, this additional electrical demand should be considered when assessing the appropriate solar array.

​

​

Which Upgrade Saves the Most Money?

 

There is no reliable answer without knowing the property.

​

A homeowner with a large unshaded roof and high electricity consumption could achieve excellent value from solar.

​

A homeowner replacing an expensive or inefficient heating system could benefit substantially from a heat pump.

​

Another property might obtain better initial value from spending considerably less money on loft insulation, heating controls or draught reduction.

​

The correct comparison is therefore not simply:

Solar versus heat pump.

​

It is:

Where will the next pound spent on this particular home deliver the greatest benefit?

​

That is a completely different question.

​

​

Should I Borrow Money to Install Solar Panels?

 

Financing affects whether any home improvement represents good value.

​

A solar system may produce worthwhile long-term savings, but expensive borrowing can reduce or even remove some of that financial benefit.

​

The same applies to heat pumps, batteries and other major energy upgrades.

​

When comparing options, homeowners should consider:

• installation cost

• available grants

• financing cost

• expected energy savings

• likely ownership period

• maintenance

• future energy requirements

​

The cheapest installation is not necessarily the best investment, but neither should projected savings be considered without including the cost of funding the system.

​

​

What If I Plan to Move House?

 

How long you expect to remain in the property matters.

​

If you intend to stay for many years, you have a longer period over which to benefit from lower energy costs.

​

If you expect to move soon, the calculation becomes more complicated.

​

Energy improvements may make a home more attractive to future purchasers, particularly where they reduce running costs or provide convenient features such as EV charging.

​

But homeowners should be cautious about assuming that every pound invested will automatically be recovered through a higher sale price.

​

The primary financial benefit should usually come from using the technology, not simply hoping it increases the property's value.

​

​

Are Solar Panels Worth It Without a Battery?

 

They can be.

​

Battery storage is not essential for a successful solar installation.

​

A household with substantial daytime electricity consumption may already be able to use a high proportion of the electricity generated.

​

Someone working from home, for example, may use electricity throughout the day for computers, cooking, washing, appliances and potentially EV charging.

​

Another household that is empty from early morning until evening may make greater use of battery storage.

​

Again, household behaviour matters.

​

​

Are Solar Panels Worth It on an East or West-Facing Roof?

 

Potentially, yes.

​

A south-facing roof may provide the highest overall generation, but east and west-facing installations can still be very useful.

​

An east-west arrangement can also spread generation across more of the day.

​

East-facing panels can provide more electricity earlier in the day, while west-facing panels continue generating later into the afternoon.

​

This may actually correspond well with some households' electricity consumption.

​

​

So, Is It Worth Getting Solar Panels?

 

For a home with a suitable roof and reasonable electricity demand, solar panels are certainly worth investigating.

​

They are one of the few home improvements capable of generating something the household would otherwise have to purchase continuously: electricity.

​

But whether the investment is attractive depends on the individual property, installation cost and how the household uses energy.

​

The best solar system is not necessarily the one with the most panels.

​

It is the one designed around the home.

​

​

And Is a Heat Pump Worth It?

 

Potentially, yes — particularly when considered at the right point in the life of the property and its existing heating system.

​

A heat pump can provide a route towards low-carbon heating and can work particularly well alongside improved insulation, solar PV and smart energy systems.

​

But it requires more careful property-specific design than simply replacing one boiler with another.

​

​

Don't Start With the Technology

 

This is one of the most important principles behind APN Green Homes.

​

Homeowners are constantly being encouraged to buy individual technologies:

Solar panels.

Heat pumps.

Batteries.

EV chargers.

Better windows.

Insulation.

Smart controls.

​

But the first question should not be:

What should I buy?

​

It should be:

What does my home actually need?

​

There may be five worthwhile improvements available, but the order in which they are carried out can make a substantial difference to the overall result.

​

​

Find the Best Investment for Your Home

 

A £10,000 improvement that looks attractive in isolation may not necessarily be the best place to spend the next £10,000 on your particular property.

​

Perhaps solar is the obvious first investment.

​

Perhaps reducing heat loss should come first.

​

Perhaps the boiler should remain for another five years while solar and battery storage are installed.

​

Or perhaps an ageing heating system means the heat pump decision needs to be made now.

​

Every home is different. Your green home plan should be too.

​

APN Green Homes creates a practical blueprint for improving your home using today's energy-saving and low-carbon technologies — prioritised around your property, your budget and your future plans.

​

Instead of asking simply “is it worth getting solar panels?”, we help you answer the more important question:

​

What are the best green home investments for my property — and in what order should I make them?

​

​
